WATER CUT-OFF.

Specication of Letters Patent.

Patented Jan. 14, 1 908.

Application filed May I8. 1907. Serial No. 374x348.

To all whom it may concern:

Be it known that I, WILLIAM Z. BROWN, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented a new and useful Water Cut-OH, of which the following is a specification,

This invention relates to improvements in cut-offs whereby the flow of water to a cistern or other source of consumption may be controlled, and it has for its object to provide an improved device of this character that is composed of a few simple parts that may be readily and cheaply manufactured and assembled, the arrangement of the parts enabling them to accommodate themselves to temperature variations that cause expansion and contraction .of the piping to which the cut-off is litted, and other objects of the invention are to provide an improved locking device for effectually retaining the valve in the desired adjusted position and one that is capable of being manufactured with the greatest facility.

To these and other ends, the invention comprises the various novel features of construction and combination and arrangement of parts, which will be hereinafter more fully described and pointed out particularly in the appended claims.

In the accompanying drawing 1-Figure 1 represents a vertical section of a water cuto' constructed in accordance with the present invention. Fig. 2 shows a portion of the cut-ofi" in elevation, as viewed from the right of Fig. 1. Eig. 3 represents a section on the line 3 3 of Fig. 1. Fig. 4 represents a section on the line 4 4 of Fig. 1`

Corresponding parts in the several i'igures are indicated throughout by similar characters of reference.

The cut-off shown in the present embodiment of the invention is composed of an upper connection section 1 `to which the piping leading from the roof or other source of water supply is connected, a branch section 2 having the branches 3 and 4, one of which usually serves as a discharge while the other communicates with the cistern or other receptacle to be filled.

The upper and lowerl sections are connected by an intermediate section 5 which has substantially the form of a attened cone, the upper end thereof receiving the upper I connecting portion 1, and the lower, or enlarged end, receiving the branched section 2,

the upper edge of the latter being substantially oval-shaped to conform to the outline of the lower edge of the intermediate section, one of these sections fitting within the other and having rivets, or similar devices, 6 for securely fastening them in cooperative relation.

Arranged within the intermediate section is a valve 7 which controls communication between the upper section 1 and the branches 3 and 4, the upper end of the valve being pivotally attached so that it remains in line with the upper section while its lower end is directed toward either of the branches. The valve, in the present instance, is supported by a bolt 8 which serves as a pivot pin, and, as it passes through the adjacent portions of the intermediate and upper sections, it also serves to secure these parts in cooperative relation.

In order to retain the valve in either of its adjusted positions, it is preferable to employ a suitable locking device, that shown in the present instance comprising a link member 9 having one end doubled to form an eye that receives an attaching staple 10 secured to one side of the valve, the link member operating through a keyhole slot 11 formed in one side of the intermediate section, the reduced portion 12 of the slot being of a width sufficient to accommodate the outer end of the member, the end 13 of the doubled portion being arranged to engage the inner side of the metal surrounding the slot when the valve is in the position shown in Fig. 3. The outer end of the member is provided with a weight 14 which serves to retain the member in two locked positions, that is to say, when the valve is in the position shown in Fig. 3, the weight serves to retain the outer end of the member in the narrowed portion of the slot, the portion 13 of the member engaging the metal at one side of the slot, the parts being unlocked by lifting the outer weighted end of the member and drawing it through the slot of the intermediate section, and when the valve assumes the position shown in full lines in Fig. 1, the eye portion of the locking member will slip down on the staple 10 after the latter has passed through the slot, the locking member being thereby interposed between the staple and the outer side of the casing, the weight serving to retain the locking member in locked position.

A water cut-off constructed in accordance with the present invention may be manufactured very cheaply of galvanized iron, or other suitable material, it being composed of a few parts so constructed that they may be readily assembled and riveted or otherwisesecured in a way that will avoid soldering and will permit expansion and contraction of the parts due to temperature variations and other causes, and the bolt 8 not only serves the dual function of connecting the intermediate and upper sections and providing a pivot for the valve, but it also serves to arrest masses of ice which fall through the upper piping and would otherwise clog and perhaps prevent operation of the valve.

The slot through which the locking member operates serves as a vent to permit an air circulation through the piping that will dry it and thereby prevent rotting, an additional vent l5 being preferably provided in the opposite side of the intermediate section of the casing so that when one is closed by the valve, the other will be unobstructed.

What is claimed is l. In a water cut-off of the character described, the combination with a casing having a slot in one of its walls provided with an enlarged portion, and a valvemounted to operate in the casing and having an attaching portion arranged to operate through the said slot, of a locking member having an enlarged portion capable of passing through the enlarged portion of the slot and coperating with the walls of the casing adjacent to the reduced portion thereof, the said member being pivotally connected to the said attaching portion and movable longitudinally thereon for locking and unlocking the valve relatively to the casing.

2. In a water cut-off, the combination with a casing having a keyhole slot in one of its walls, and a valve mounted to operate in the casing and having a staple thereon arranged to register with and extend through the said slot, of a locking member pivotally attached to the staple and operable longitudinally thereof to interpose an enlarged portion on the member between the staple and the wall of the casing adjacent to the narrowed portion.

3, In a water cut-off, the combination with a casing having a keyhole slot in one of its walls, and a valve pivoted to turn in the casing and having a staple thereon, of a locking member having its inner end doubled and forming an eye to slidingly receive the staple, one end of the doubled portion being arranged to engagefthe inner side of the casing adjacent to the slot when the outer end of the member is resting in the reduced portion thereof, the staple on the valve being arranged to operate through the slot and to receive the doubled portion of the locking member between it and the outer side of the casing, and a weight on the outer end of the locking member and serving to retain the latter in both locked positions.

4. In a device of the character described, the combination with'a casing provided with a vertical slot in one of its walls having an upper enlarged portion and a lower reduced portion, and a valve mounted to turn in the casing, of a locking member having its inner end pivotally attached to the valve and capable of a vertical movement relatively thereto, the locking member having an inner enlarged portion wider than the reduced portion of the slot and narrower than the enlarged portion thereof arranged to engage the inner wall Vof the casing when the valve is in one position, and to pass through the slot and move 'downwardly to engage the outer walls of the casing adjacent to the reduced portion of the slot when the valve is in a different position.

5. In a device of the character described, the combination with a casing having a keyhole slot therein, and. a valve pivoted within the casing having a staple thereon adapted to operate through the enlarged and reduced portions of the slot, of a locking member having its inner end doubled and pivotally and slidably engaging the staple on the valve, the doubled portion being narrower than the enlarged portion of the slot and wider than the reduced portion thereof and ada ted to engage the inner wall of the casing w en the valve is in one position, and slidable vertically on the staple when the latter projects through the slot, the doubled portion of the locking member moving between the staple and the adjacent outer wall of the casing and locking the valve in a different position.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

. WILLIAM Z. BROWN.
